This was taken with a Canon 5D Mark II and a sigma 28-300mm zoomed to 270mm using a tripod set on the island in the middle of London's Picadilly Circus. The people are waiting to cross, as instructed by the traffic light on the left, while the bus speeds around the traffic circle. There's another still object to the left of the person that is the route sign on another bus waiting at a red light facing the camera behind the passing bus. I used a narrow aperture (f/5.7) to be able to use a longer exposure to get the blur without washing out. I did use adobe camera raw to darken the image because it was still pretty bright.
